2 people: my (ex) best friends wife and my (female) best friend

So my best friend from high school and I used to be close but when I turned to him for help a few years ago he flat out told me he didn't want to hear about it. I felt pretty shitty and betrayed by that so when his wife started coming to me with problems she was having with him I decided I owe that AH nothing and we started having an affair. Now that is not the only reason we hooked up (she is super cute with a great body and her inhibitions are dropped when we jlhook up). We never use protection and we kinda build the risk into out dirty talk. Basically it is something I am actively working on atm

The other is a friend I met in college. We nearly hooked up a few times back then but then just became super close friends. However since lockdown started we have become super flirty and more than once talked about how we both kinda have a breeding kink. We live in different cities so haven't seen each other much irl but the last time I went to her city for a weekend we nearly hooked up. Been obsessed with the idea of breeding her since then
